FLOOR SCREEDING EXPERTS DUNSTABLE
A dependable floor screeding specialist in Dunstable will have experience and knowledge to help you achieve a perfectly finished floor in whatever size room you are renovating. They'll assess your project and determine the appropriate type of screed you need and the best technique for applying it.
It might be necessary, depending on the intended use of the space, for a survey by a structural engineer to conform to building regulations on flex strength, point loadings and load bearing of the screed floor.
Qualified and skilled tradesmen are necessary for a successful result and will extend the lifespan of your floor by using the correct sort of screed for your room's allocated purpose. There are many different types of floor screed and picking the appropriate mix and installation process is crucial to achieve a top quality floor that is durable and fit for purpose.
Before choosing a floor screeding company from those based in the Dunstable area, ask to what standard of finish they are basing their quotation, and also ensure that you get two or three quotes from different companies. The quote could be based on what is called the Surface Regularity, or SR number. Each of the three SR levels offer different standards of finish, with SR1 being the highest quality, with the smallest amount of deviation over the area. Any error in the screeding may cause problems in laying flooring owing to flat spots, indentations, ridges in the floor surface.
All Dunstable screeding companies have to stick to British Standards (BS8204) and should have some kind of accreditation from screeding material and equipment manufacturers, for instance Flowcrete, Gypsol, Cemfloor. A company holding accreditations demonstrates that they've been assessed and trained in using these products and can provide a high standard of service in all areas of their installation.
For the screeding of floors in hospitals, factories, schools, shopping centres, pubs and warehouses, dedicated commercial screeders in Dunstable will be needed.
TYPES OF SCREED
Standard Screeds - Used in residential projects where the combination of cement and sand is good for everyday floor traffic use. This mix uses a five to one ratio of sand to cement. Once laid this 5:1 ratio dries at a rate of 1mm per day.
Fast Drying and Advanced Drying Screeds - If there is a need to press ahead urgently with the work owing to time constraints, this screed dries more speedily than standard screeds. Drying out at a rate of three to seven millimetres, determined by the specialised mix, they're typically a fibre reinforced screed and are perfect for flooring projects which have tight deadlines.
Polymer Screeds - Provides an extremely high level of strength with a minimal thickness. Due to their different chemical compositions, these polymer screeds have varying curing times which can be verified by checking manufacturer's product guidelines.
Fibre Reinforced Screed - The favourite choice of professional contractors for use with under floor heating systems. This is because of the increased durability and protection against thermal cracking and shrinkage offered by the fibres within the screed. At around 1mm per day, it has a similar drying rate to standard floor screed.
Liquid or Self-Levelling Screeds - A latex and cement material which can produce the highest standard of finish to SR1 levels. Typically used to finalise a poor substrate level or damaged floor in order to lay a new flooring surface, such as tiles over it. These can be as little as one millimetre thick, and thanks to the latex polymers, will still provide a high strength finish.
Industrial and Heavy Duty Screed - Where levels of traffic are high or heavy loading on the floor is required, heavy duty screeds offer maximum durability and strength.
SCREEDING PREPARATION AND INSTALLATION
To guarantee the screeding is of a high quality finish that's hard wearing and durable, time should be devoted to fully preparing the area prior to any screed being laid. It is important that any contaminants such as paint, grease, debris or oil is removed from the base before pouring any screed, since these can affect the adhesion process that a good quality screed demands.
If cleansing products were used it's vital to remove any residues of soap etc, and leave the surface to dry naturally. It's vital to fix any crevices or cracks in the base to stop them being mirrored and "travelling" upwards into your newly screeded floor. A reliable Dunstable screeding specialist will pick up on these issues during a site survey and make certain all preparations are completed before moving on to the next steps in the floor screeding process.
A DPM (damp proof membrane) will be applied after the preparation work has been concluded to stop ground moisture getting into the flooring materials and screed. There might be 2 or 3 layers of different thickness polythene to act as barriers between the screed and the insulation layer.
A further air-tight barrier could be required if your property is in an area that is regarded as susceptible to radon gas. This can be just a simple airtight membrane, or in more serious situations a ventilation system is installed beneath the screed to draw out any inflow of radon gas from the ground.
Once the base has been prepared and all DPMs installed, a primer or sealant is then put on. A primer assists in the screed bonding correctly to the base surface and different varieties exist based on which kind of screed is being applied. On account of their special nature, only trained screeding contractors in Dunstable are capable of using them safely and correctly and through the use of equipment that is made for this task.
Now is the time that under floor heating can be installed and laid out in the correct manner. The cables and heating pipes are firmly attached to insulation panels to stop any movement and make certain they are laid in the correct position. Underfloor heating is one of the most effective ways to heat a room and an expertly installed system should deliver even level of warmth all over the floor.
Naturally, if you're not installing under floor heating, you can ignore this stage and get on with applying the screed. Your screeding company will have given you advice on which kind of screed is appropriate for your needs, in line with your intended use of the room area. Remember that even quick drying screeds have a minimum of twenty four hours before you're able to walk on any laid surface and at least seventy two hours before any flooring can be laid. If you are using heavy duty or standard screeds the setting time is longer and you must observe the manufacturer's guidelines so as to get the best finish for your floor.
You can test the SR level of the finished screed as soon as it is set enough to walk on. Through the use of a 2m straight-edge the floor surface is checked for any ridges, deviations and dips in the screed surface.
- SR1 - SR1 is the best standard and permits only three millimetres of deviation from the straight-edge.
- SR2 - The normal standard flooring in industrial and commercial builds is classed as SR2 and has a maximum possible deviation of 5mm across the entire screed.
- SR3 - SR3 is basic utility standard where a perfect finish is not needed. This specification can have a maximum permissible deviation of 10mm.
If your screed floor has been installed with particular loading in mind then a qualified structural engineer will be needed to carry out the tests. The assessment will ensure your new screed is viable for the load bearing requirements laid out in the original site survey. An assessment called the drop hammer test will be carried out at several areas on the screed and the results recorded. Only certified structural engineers respecting the BS8204 guidelines are permitted to perform these tests and sign off on the structural integrity of the screeding.
